this is implemented on top of v4 memory hotplug series: http://lists.gnu.org/archive/html/qemu-devel/2014-06/msg00129.html
Series adds following QMP commands: - query-memory-devices - query-acpi-ospm-status and event: - ACPI_DEVICE_OST Which could be used by management tools to query current state of memory devices (implemented only for PCDIMMDevice so far) and a related ACPI view of corresponding status of slots (ACPI Memory Device objects). git tree for testing: https://github.com/imammedo/qemu/commits/memory-hotplug-OST Igor Mammedov (5): qmp: add query-memory-devices command acpi: introduce TYPE_ACPI_DEVICE_IF interface acpi: implement ospm_status() method for PIIX4/ICH9_LPC devices qmp: add query-acpi-ospm-status command qmp: add ACPI_DEVICE_OST event handling docs/qmp/qmp-events.txt | 10 ++++ hw/acpi/Makefile.objs | 1 + hw/acpi/acpi_interface.c | 15 +++++ hw/acpi/ich9.c | 7 +++ hw/acpi/memory_hotplug.c | 60 +++++++++++++++++++++- hw/acpi/piix4.c | 11 ++++ hw/isa/lpc_ich9.c | 3 + hw/mem/pc-dimm.c | 39 ++++++++++++++ include/hw/acpi/acpi_dev_interface.h | 43 +++++++++++++++ include/hw/acpi/ich9.h | 3 + include/hw/acpi/memory_hotplug.h | 1 + include/hw/mem/pc-dimm.h | 2 + include/monitor/monitor.h | 1 + monitor.c | 1 + qapi-schema.json | 94 ++++++++++++++++++++++++++++++++++ qmp-commands.hx | 49 ++++++++++++++++++ qmp.c | 31 +++++++++++ stubs/Makefile.objs | 1 + stubs/qmp_pc_dimm_device_list.c | 7 +++ 19 files changed, 378 insertions(+), 1 deletions(-) create mode 100644 hw/acpi/acpi_interface.c create mode 100644 include/hw/acpi/acpi_dev_interface.h create mode 100644 stubs/qmp_pc_dimm_device_list.c
